Here are the injuries we're monitoring after Sunday's Week 8 action.
Nick Fairley, DT, Detroit Lions (knee): The Lions beat the Falcons very early Sunday, but they may have paid a high price on their way to a 6-2 mark and first place in the NFC North. Fairley was carted off the field with a right leg injury following a collision with teammate Ndamukong Suh, and according to head coach Jim Caldwell, the prognosis is not good.
"I'm not quite certain where he is right now," Caldwell said. "But obviously, when you're carried off the field, it's not the greatest news. We'll see what the doctors say about him."
There will be more conclusive news on Fairley early this week, but TheMMQB's Peter King is hearing the injury is "bad," which would be really unfortunate -- Fairley is in the last year of a rookie contract that gives him a base salary of $1,723,500, and he's playing very well this season after going through some concentration lapses earlier in his career.
Lamarr Houston, DE, Chicago Bears (knee): Houston went down after celebrating a sack in Chicago's blowout loss to the Patriots, and, per multiple reports, he suffered a season-ending torn ACL. Houston has struggled to get sacks since the Bears signed him to a five-year, $35 million contract in March.
Brian Quick, WR, St. Louis Rams (shoulder): Quick exited Sunday's loss to the Chiefs with a shoulder injury and, according to ESPN's Adam Schefter, the injury will sideline him the rest of the season. The third-year wideout is second on the team in targets (39). St. Louis will turn to tight end Jared Cook and wideout Kenny Britt to fill the void.said after the loss
Jon Beason, LB, New York Giants (toe): The man in the middle of the Giants defense will require toe surgery that'll knock him out for the rest of the season. Beason's in the first year of a three-year deal signed this spring.
Jake Long, OT, St. Louis Rams (knee): According to Pro Football Talk, the Rams fear that the injury Long suffered against the Chiefs in a 34-7 loss could be season-ending. If that's the case, head coach Jeff Fisher might be forced to move rookie Greg Robinson to the left tackle spot, when Robinson has struggled to get on the field at times from a performance perspective. If it's a torn right ACL, it's the same one Long tore last season, and at age 29, there has to be concern about his NFL future.Jeremy Hill
Doug Martin, RB, Tampa Bay Buccaneers (ankle): Martin's injury history is unfortunately long and varied, and he managed just 27 yards on 10 carries before he left the Bucs' loss to Minnesota with an ankle injury in the third quarter. Martin has played in just five games this season, and his yards per carry has dropped from 4.6 to 3.6 to 2.9 in the last three seasons. Once thought to be Tampa Bay's sparkplug, Martin still has the talent, but he's having trouble holding up physically.
